OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION IN A

Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron. Depending on its content of volatile matter, the coal is part-ly blown into the ...

06/09/2020  For direct iron ore regeneration, the main kiln used is the rotary kiln. The spherical or spongy spherical parts, which are produced by the direct reduction of iron ore (Direction Reduce Iron) and the removal of oxygen, are called sponge iron. Sponge iron has a high grade of iron (84 to 95%) and one of the reasons for its prevalence is the shortage and increase in the price of iron waste and ...

Accretion Control in Sponge Iron Production Kiln using ...

The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed. A temperature profile ranging from 7000C-10500C should be maintained along the length of the kiln at different zones. As ...

Sponge Iron - an overview ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...
